Three-dimensional porous graphene networks expand graphene-based electronic device applications
Yoshikazu Ito, Yoichi Tanabe, Katsuaki Sugawara +5
Graphene with excellent 2D characters has been required to expand their potentials for meeting applicational demands in recent years. As one avenue, several approaches for fablicat…
New class of flat-band models on tetragonal and hexagonal lattices: Gapped versus crossing flat bands
Tatsuhiro Misumi, Hideo Aoki
We propose a new class of tight-binding models where a flat band is either gapped from or crossing right through a dispersive band on two-band (i.e., two sites/unit cell) tetragona…
Electric Properties of Dirac Fermions Captured into 3D Nanoporous Graphene Networks
Yoichi Tanabe, Yoshikazu Ito, Katsuaki Sugawara +12
Graphene, as a promising material of post-silicon electronics, opens a new paradigm for the novel electronic properties and device applications. On the other hand, the 2D feature o…
Magneto-orbital effect without spin-orbit interactions --- noncentrosymmetric zeolite-templated carbon structure
Takashi Koretsune, Ryotaro Arita, Hideo Aoki
A peculiar manifestation of orbital angular momentum is proposed for a zeolite-templated carbon system, C36H9. The structure, being a network of nanoflakes in the shape of a "pinwh…
Accessing surface Brillouin zone and band structure of picene single crystals
Qian Xin, Steffen Duhm, Fabio Bussolotti +6
We have experimentally revealed the band structure and the surface Brillouin zone of insulating picene single crystals (SCs), the mother organic system for a recently discovered ar…
Spin-density functional study of the organic polymer dimethylaminopyrrole: A realization of the organic periodic Anderson model
Yuji Suwa, Ryotaro Arita, Kazuhiko Kuroki +1
While the periodic Anderson model (PAM) has been recognized as a good model for various heavy f-electron systems, here we design a purely organic polymer whose low-energy physics c…
